Study Notes
Linux Operating System
- A repository is a collection of software for a Linux distribution on a server.
- The package manager updates the operating system and other software periodically.
- Linux is flexible and easily customizable, allowing users to change the desktop, menu position, status bar position, style, and more.
- Linux has excellent support, with thousands of forums and millions of people ready to help open source software users.
Advantages of Linux
- Linux is free from viruses, eliminating the need for anti-virus software and reducing the risk of data loss.
- Linux makes it easy to keep software up-to-date, preventing data redundancy and ensuring single copies of files.
Database Management System (DBMS)
- A database is a collection of organized data that can be shared among users with authorized access.
- DBMS provides data privacy, allowing only authorized users to access data according to privacy constraints.
- DBMS automatically takes care of backup and recovery, ensuring data is restored after a crash or system failure.
- DBMS reduces application development and maintenance time.
Primary Memory Storage
- No specific information provided about primary memory storage.
Linux vs Windows
- Linux is different from Windows, but no specific differences are mentioned.
Network Protocols
- LAN (Local Area Network) is a network that connects devices in a limited geographical area.
- MAN (Metropolitan Area Network) is a network that connects devices in a larger geographical area, such as a city or town.
- WAN (Wide Area Network) is a network that connects devices over a wide geographical area, such as a country or continent.
Introduction to DBMS
- A database is a collection of organized data that can be used to make informed decisions.
- Data is raw facts, while information is processed data that helps in decision-making.
- Examples of databases include phone diaries, medical records, and student records.
- DBMS provides an organized way to store and retrieve data.
